BREASTPIN.

SPECIFICATION forming part of Letters Patent No. 440,081, dated November 4, 1890.

Application filed April 4, 1890- Serial No. 346,530- (No model.)

H To on whom it may concern:

Be it known that I, GEORGE K. WEBSTER, of North Attleborough, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Breastpins and the Like; and I do hereby declare that the following is a full, clear, and exact description of the same.

The object of my invention is to provide means for securing the catch and pin-joints of breastpins and like articles of jewelry in such a manner as to prevent the turning action of the joints in the material of which the ornament is made. Ordinarily these fast enings are secured to the pearl or other simi-- lar material constituting the body of the ornament by simply drilling through from one side to the other, passing the stem of the pin which is connected to the joint or catch through and heading it down upon the front side of the ornament, leaving it thus exposed, or covering it, as may be found desirable; but in this method of securing the catch or pin-joint it has been found that after very little use the stems becomeloose and are liable to turn, so as to get outof alignment with the opposite part.

To this end my invention consists in providing the stem of the catch or the stem of the pin-joint with a squared shoulder and fitting this shoulder with a corresponding depression 0r countersink in the under face of the ornament, the stem passing through, as in the ordinary way, this arrangement preventing any lateral displacement or swiveling movement, as referred tqabove.

In the accompanying drawings, Figure 1 represents a sectional View of a breastpin provided with my improvement, and Fig. 2 is a plan View.

While I have shown my invention as applied to breastpins, I desire it be understood that I no not limit myself in this respect, but

may utilize the idea for use with the stems of ear rings, studs, and articles of a like nature.

In the drawings, A represents the ornament, which is provided with a catch a and a pin 79, which is pivoted between the walls I), secured to or formed with the stem 0, constitutingthe pin-joint. A hole is drilled through the ornament near one end, and through this the round stem of the catch passes. This stem is provided with a shoulder, as shown at d, and this shoulderhas flattened sides. A countersink corresponding to the shape of the shoulder is formed in the under face of the ornament at the entrance of the round opening, and thus when the end of the pin is headed down on the face of the ornament the shoulder fits its countersink snugly, and all turning of the catch is prevented.

While I have described the stem of the catch as round and provided with a square shoulder, I do not limit myself to this con struction, as itis possible to obtain the same results by providing a square hole adapted to receive a stem square in cross-section. The stem of the pin-joint may be made in precisely the same manner; but instead of forming a squared shoulder 011 the stem the countersink may be made of sufficient depth to engage the flattened walls of the cap, between the walls of which the pin is pivoted. As these walls are approximately parallel to each other, they serve the same purpose as the squared shoulder of the catch.

Instead of passing the stem entirely through the material of the ornament and heading it down, I may in some cases drill only partly through, fasten the stem by a strong cement, the shoulder or squared stem preventing turning.

I claim as my invention- 1. In combination with the ornamental part of a breastpin, a catch having a stem, and a non-circular shoulder adapted to fit a countersink of corresponding shape, substantially as described.

2. In combination with the ornamental part of a breastpin, a pin-joint having a stem and a cup-shaped part adapted to receive the end of the pin, said cup-shaped part being noncircular in cross-section and adapted to a corresponding recess in the under face of the ornament, substantially as described.

3. In combination, a catch having a stem with a square shoulder fitting a corresponding recess, and a pin-joint having a stem, said pin-joint fitting a recess in the under face of the ornament, substantially as described.

In testimony whereof I have signed my nameto this specification in the presence of two subscribing witnesses.
